Description
CROSS REFERENCE TO RELATED APPLICATIONS
[0001] The present application claims the benefit of Chinese Patent
Application No. 202021856444.2 filed on Aug. 31, 2020, the contents
of which are incorporated herein by reference in their
entirety.
TECHNICAL FIELD
[0002] The present disclosure relates to a mechanical tool, and
more particularly, to a tool of a double-angle chamfering
cutter.
BACKGROUND
[0003] In the prior art, if a workpiece with two angles is
processed on an aperture element, two chamfering cutters are needed
to complete processing alternately. When two chamfering cutters
complete a process, the process is relatively cumbersome and the
center of an aperture is deviated. During a chamfering process, a
plurality of burrs are also difficult to clean. Currently,
chamfering at different positions at the same angle by rotating the
chamfering cutter at different angles does not provide a chamfering
process of different angles.
[0004] The Chinese patent publication number CN206854665U disclosed
an adjustable chamfering cutter and has an adjustable blade to
further complete a chamfering method of different angles. Such a
rotation causes the instability of a blade at different degrees.
When in use, the cutter is adjusted and fixed with a nut first and
then chamfered. Although the number of blades is reduced to a
certain extent, there is no process of substantially changing a
chamfer.
SUMMARY
[0005] In order to overcome the forgoing drawbacks, an objective of
the present disclosure is to provide a tool for a double-angle
chamfering cutter with a double-angle chamfering function.
[0006] The present disclosure relates to a tool for a double-angle
chamfering cutter, including a cutter handle, a cutter body, and a
cutter head. The cutter handle is connected to one end of the
cutter body via a snap-fit connection device, and the other end of
the cutter body is in threaded connection with the cutter head. A
cutter box is arranged on the cutter head, and a chamfering blade
is arranged on the cutter box.
[0007] Preferably, a hole is arranged inside the cutter handle. The
diameter of the hole is a half of the diameter of the cutter
handle. A groove channel is provided on one side of the hole wall.
The cutter body enters along the inner hole of the cutter handle. A
bump on the body falls into the groove channel. A aperture is
arranged to facilitate the cutter body to enter the cutter handle.
The groove channel is arranged to help catch the bump connected to
a sliding track of the cutter body, thereby connecting the cutter
handle and the cutter body.
[0008] Preferably, one end of the cutter body is provided with the
sliding track perpendicular to the cutter body. The sliding track
and the side of the cutter body form a cavity. A spring is arranged
inside. One end of the spring is fixedly connected to the side of
the cutter body, and the other end of the spring is fixedly
connected to a bump outside the cavity. The bump is fixedly
connected to the sliding track. The elasticity and tension of the
spring help the bump to expand and contract. The design of the
sliding track facilitates the expansion and contraction of the bump
along a certain direction and track.
[0009] Preferably, the design of a button of a square region on the
cutter handle is attached to the groove channel. The middle of the
sliding track inside the cutter body is hollow. When the bump falls
into the groove channel, the bump can be pressed to the inner side
of the cavity of the cutter body by pressing the button. This
achieves a good effect of controlling the cutter body by the
button.
[0010] Preferably, the cutter body is provided with a chamfering
blade A and a chamfering blade B at one end away from the cutter
handle. The chamfering blade A and the chamfering blade B are
connected to the cutter body via a locking screw, respectively. The
chamfering blade A and the chamfering blade B are positioned on
both sides of the cutter body, respectively. The chamfering blade A
and the chamfering blade B are exactly the same two blades.
[0011] Preferably, the chamfering blade is provided with two
inclined ports in a vertical direction of the cutter body. The
upper port is inclined by 30 degrees, and the lower port is
inclined by 60 degrees. Two inclined blades are provided on the
chamfering blade. Cutting can be performed in two inclined angles
via one process. In addition, it can be ensured that center focuses
of cutting in two different angles is the same on the same
blade.
[0012] The present disclosure has the following beneficial
effects:
[0013] 1. The cutter body of the tool for the double-angle
chamfering cutter has two chamfering blades on the cutter body. Two
chamfering blades are positioned at symmetrical positions, which is
convenient to ensure that a cutting angle formed by the
corresponding position in the middle of a workpiece is consistent
in a process that a double-angle operation is completed, thereby
improving the precision of cutting the workpiece.
[0014] 2. The sliding track is mounted in the cutter body of the
tool for the double-angle chamfering cutter. Two ends of the
sliding track and three fixing connection points of the spring fix
the position of the bump, and further achieves the smoothness of
expansion and contraction of the bump at the same time. A rolling
bead can be positioned in the sliding track to increase the
smoothness of sliding.
[0015] 3. The chamfering blade of the tool for the double-angle
chamfering cutter is provided with two inclined ports with
different angles from the vertical direction of the cutter body,
which is beneficial to cutting the workpiece at double angles at
the same time. The problem of changing the angle of the blades by
three to four times is eliminated, thereby saving time and
improving process efficiency.

DESCRIPTION OF THE INVENTION
[0021] The technical solutions in embodiments of the present
disclosure are described clearly and completely below in
conjunction with the drawings in the embodiments of the present
disclosure. Obviously, the described embodiments are only a part of
the embodiments of the present disclosure, rather than all the
embodiments. Based on the embodiments of the present disclosure,
all other embodiments obtained by the person skilled in the art
without creative labor shall fall within the protection scope of
the present disclosure.
Embodiment 1
[0022] As shown in FIG. 1, there is provided a tool for a
double-angle chamfering cutter, including a cutter handle 1 and a
cutter body 2. The cutter handle 1 is connected to the cutter body
2 via a snap-fit device. FIG. 2 shows a partial schematic diagram
of a cutter body 2 clamped into the cutter handle 1. One end of the
cutter body 2 is provided with a sliding track 5 perpendicular to

body 2 enters along of the aperture inside the cutter handle 1. The
bump on the cutter body 2 falls into the groove channel. The outer
part of the cutter handle 1 has a square region. The square region
is provided with one button 6. The inner part of the button 6 is
connected to the top of the bump. When the cutter body 2 enters the
cutter handle 1, the bump falls into the groove channel, and the
cutter handle 1 and the cutter body 2 can be fixed. FIG. 3 shows a
partial schematic diagram of a structure of a double-angle
chamfering blade. FIG. 4 shows a cross-sectional diagram of a tool
for a double-angle chamfering cutter. The end of the cutter body
away from the cutter handle is provided with a chamfering blade A 3
and a chamfering blade B 4. The chamfering blade A 3 and the
chamfering blade B 4 are at the corresponding positions on both
sides of the cutter body 2. The chamfering blade A 3 and the
chamfering blade B 4 are at 180 degrees. The chamfering blade A 3
and the chamfering blade B 4 are connected to the cutter body 2 via
a locking screw 7, respectively. Two inclined ports are both
provided on the chamfering blade A 3 and the chamfering blade B 4.
An upper port forms an included angle of 30 degrees with the cutter
body 2 in a vertical direction. The lower port forms an included

Embodiment 2
[0023] This embodiment is distinct from Embodiment 1 in that a
chamfering blade A and a chamfering blade B of this embodiment are
fixed to a cutter body by welding, respectively. The chambering
blade A and the chamfer blade B can be fixed and are not easily
loosen by the welding, which is more beneficial to the fixation of
the blade. The blade is not easy to move during a plurality of
operations. However, inconvenience is that the surface of the blade
body is easily damaged when the blade is replaced, and a process of
removing the blade is complicated.

[0024] As shown in FIG. 3, a partial schematic diagram of a
structure of a cutter body, this structure is a part of a cutter
body that is clamped into a cutter handle. Embodiment 3 is distinct
from Embodiment 1 in that a sliding track contains a folded sliding
sheet instead of a rolling bead. The sliding sheet is fixedly
connected to a bump. In the process of sliding, the expansion and
contraction of the folded sliding sheet drives the bump to contract
and expand. The stretchability of the sliding sheet is relatively
good. The expected expansion and contraction effects can be
achieved at the same time. The flexibility and the smoothness of
the rolling bead are better than those of the sliding sheet. The
best components can be selected according to the current price
during a selection process.
[0025] Finally, it should be noted that the forgoing embodiments
are only used to illustrate the technical solutions of the present
disclosure and are not to limit thereto. Other modifications or
equivalent substitutions made by the person skilled in the art to
the technical solutions of the present disclosure shall fall in the
